Product Description

Product Description

Step Drill Bit

Step drill bits are mainly used to cut holes in metal. They are also used to drill wood, acrylic, and other plastics, but one limiting factor of the step drill bit is that they are only suitable for cutting thin materials, such as sheet metal. The material has to be 5mm thick or thinner for the step drill to be able to drill through it.
 
Step drill bits can help to both drill holes, and also enlarge current holes. This is because of the shape of the drill bit, allowing it to efficiently enlarge holes to the correct size with the help of the step design.
 
Step drill bits are great for cutting through plastic, it offers a very smooth cut and finish without damaging the hole or material. They are also great at cutting through thin metal, as it cuts it very smoothly compared to twist drills, and slowly shaves off the metal leaving a smooth beveled edge to the metal.
